Student answer (Band 4.5)

So bamboo fabric is made By planting bamboo plants ( spring) Then after one season of planting in spring we harvest the plants in Autumn then after getting harvested they are brought into factories in which they are cut into strips then we soften the stripes by adding water and amine acide then after that we filter it by separating long fibers from the liquid which can so much time because separating long fibers from liquid is very difficult and challenging after separating we crush the strips to make the liquid a pulp Then after making it into a pulp people spin the pulp and after some time it turns into a Yarn after that we weave the yarn to make comfortable clothes for us after weaving they are brought by shopkeepers and we get the comfortable clothes we getting today

in conclusion it's planting, harvesting, cutting, filtering separating,spin wpim and weave

Task Achievement / Task Response — Band 4.5

The student attempts to summarise the diagram showing the process of manufacturing fabric from bamboo, covering several of the main stages from planting to weaving. However, the response contains significant flaws in task completion. First, the description includes the wrong order for some steps; for instance, the student states that the strips are crushed to make pulp after filtering, whereas the diagram shows crushing occurring before filtering. Furthermore, the response includes unnecessary personal commentary and speculation not present in the visual data, such as noting that filtering 'can take so much time' and that clothes are 'brought by shopkeepers'. The overview provided at the end is merely a list of words rather than a summary of the main trends or stages. Consequently, the task is only partially addressed.

Coherence and Cohesion — Band 4.0

The text suffers from a severe lack of punctuation and paragraphing, consisting almost entirely of a single massive run-on sentence in the main body followed by a disjointed conclusion. The student relies heavily on repetitive conjunctions such as 'then' and 'and then' to link clauses, creating a mechanical and exhausting reading experience. There are no clear paragraph breaks to separate the introduction, body steps, and conclusion, which makes the logical progression difficult to follow. Pronoun referencing is also occasionally imprecise, with vague transitions between ideas.

Lexical Resource — Band 4.5

The vocabulary used is overly simplistic and repetitive, relying on basic terms like 'bamboo', 'plants', 'strips', 'liquid', 'pulp', and 'clothes'. There are several spelling and word-choice errors, such as 'amine acide' instead of 'amine oxide', 'stripes' instead of 'strips', and 'spin wpim' in the conclusion. While the student attempts some topic-specific vocabulary related to the prompt (e.g., 'harvest', 'filter', 'weave', 'yarn'), the overall lexical range is very narrow and basic, struggling to maintain accuracy with less common technical terms.

Grammatical Range and Accuracy — Band 4.0

Grammatical control is weak throughout the response. The text is characterised by a complete absence of periods, capital letters for new sentences, and correct punctuation, resulting in a continuous run-on structure that strains the reader. There are frequent errors in subject-verb agreement and clause combination, such as 'we getting today'. Complex sentence structures are poorly handled, and the lack of basic punctuation causes frequent interference with readability. The range of grammar is severely limited by the inability to demarcate separate sentences.
